  • This is the most comfortable mattress I have ever had. I sleep so well on it, and the cooling gel layer stop nightly hot flashes. I shopped around before I made this purchase, and Overstock had the best price.

    Very comfortable to sleep in. Good quality foam similar to the more expensive brands. I use this in a guest room and have not gotten any complaints.

    This mattress has aided my sleep immensely. It is just the right combination of firmness and softness for me. It's hard to find that balance in a mattress and I must say that this one definitely fits the bill. I loved that it was shipped in a compact box and was ready for use in no time.

    This mattress definitely exceeded my expectations. It's exactly what I was looking for and exceptional quality for the price. The mattress is firm but the memory foam contours to your body and I've never slept better.

    This mattress is perfect! I prefer a firm mattress and was surprised to find this one to be firm with just the right amount of give when you recline back. Love the way it supports my neck and back. Still amazed that something so large fit in such a small box when shipped. Great quality... Great price... Shipped quickly... No complaints whatsoever!

    My second review. I felt like to be fair since I trashed an earlier purchase I needed to speak out when I purchased a good product. I put this on my 21 year old's Baxton Studio Bed. He is 6'1" and 200 lbs. I was reluctant to try this with no box spring. I was wrong. He said it's very comfortable and does require a box spring. Excellent value coupled with the Baxton Studio Bed!

  • Q:

    "I believe standard full size mattress measures 75 inches. According to product specs, this mattress is 78 inches long. I am concerned that this mattress may not fit in IKEA MALM full size bed frame. Has anyone tried fitting this mattress to MALM full size bed frame?"

    • A:

      I have a different full size bed frame from IKEA and the mattress definitely fits!

  • Q:

    "Does this mattress meet the US requirements for CeriPUR-US or other Certification meeting US Standards for environmental safety?"

    • A:

      I do not see this mattress matching those requirements.

  • Q:

    "Does anyone have recommendations on how to make the mattress expand more?ive had it out for 2 days now without sleeping on it and the right side is expanded to 8 inches but the left is at 6 1/2 and the top side that was curled under won't uncurl to a straight edge. I took it out of the box a day after it arrived too"

    • A:

      I had no problems with the full size I ordered and in fact I just ordered a king size as well. I opened it and positioned it flat to open for 24 hours. Then I assured the cover was aligned and not twisted and let it continue for 24 more hours. It filled the cover fully and was ready to go in 48 hours.

  • Q:

    "can this be used on a futon"

    • A:

      Oh nooooo! Lol! Is not skinny or flexible enough to be fold......even if it was skinnier I don't see it folding and if it does it won't stay fold neither. Is not a hard mattress for the body but yes for folding it. Hope this helps! :)

    • A:

      Only as a permanent bed - not to be folded into a couch. And if used on a futon frame, the futon frame should be smoothed out by plywood (or something like it) to protect the mattress from any metal futon parts (if a metal futon) and for comfort.

    • A:

      The previous answer is exactly what I would have said as well. No way.

  • Q:

    "can i put this on my existing box spring?"

    • A:

      Yes, you can put this on your existing box spring.

    • A:

      if the futon is going to be permanently lowered as in the bed position yes but wouldn't recommend in the sofa position.
